Hubert Humphrey was pretty busy in that time period with the civil rights legislation. The civil rights debates actually were going on in the late 1940s. When Hubert Humphrey was elected to the Senate and he made his famous pro-civil rights speech at the 1948 DNC. And the 1964 Civil Rights Act where Humphrey had a big role in getting that bill passed. And ending the Senate filibuster from the Southern right-wing Democrats. And helping to bring aboard some Northern Progressive Republicans. And as Vice President he had a role in getting the 1965 Voting Rights Act passed as well as Medicare health insurance for senior citizens. But I believe Hubert Humphrey's legacy in Congress was the civil rights legislation. Who without him those bills never get passed.
Hubert Humphrey had the perfect approach to civil rights, because he saw it as about human and constitutional rights. Which trumps states rights, which was of course the argument that the Southern Dixiecrat Democrats were making. That the states had the right to enforce constitutional rights as they see them. Even if it violates constitutional rights of African-Americans and other racial minorities. But the Republican Party of the 1960s even though they were the opposition party from 1961-69 and were a small minority party in both the House and Senate for the whole decade, deserve a lot of credit in Congress for those bills being passed at all.
Congressional Republicans like Senate Minority Leader Everett Dirksen, deserve a lot of credit for getting the civil rights legislation passed as well, because they don't pass in the Senate. Without Senate Minority Leader Everett Dirksen, who without him these bills never get passed in this era. Hubert Humphrey tends to get lost when we are talking about great politicians and public servants for whatever reason. But without him a lot of important legislation never gets passed. And a lot of Americans would've been denied their constitutional rights as a result, just because of their race. Which would've been a disgrace in a liberal democracy like America.
